- Naval units refuse to move back from coastal sea province, unless going into a neighboring port (playing as Austria-Hungary) [I believe this one was caught by someone else though?]
- If you accidentally merge the Austro-Hungarian fleets at the beginning of the game, and Germany chooses to send that cruiser (SMS Goeben???) to you, the ship disappears in the Bermuda Triangle, presumably because there is no more Cruiser Fleet for it to be allocated to!

- Germany playing bad events for you (could be working-as-designed, though, from what I read) when you play as A-H
- The factory display on the map is schizophrenic. The icons and tooltips don't correspond to each other, and I have a feeling it indicates plants are unemployed when, in fact, they are employed
- Fog of War on minefields hides your own minefields from you, too
- [minor] Tsingtao is German in the 1918 scenario
EDIT: Didn't notice there was a separate forum for this sort of stuff...though some of these are bugs, rather than data/setup issues.
